You share common goals with a very important person, and you should let them know that they can count on you today. Let them know that you are on their team, ready to jump in and get to work whenever they need you to: and make sure you mean it! Follow-through is essential when you're dealing with influential folks. Teamwork is not only a great morale booster, but it's a great way to build better relationships with people who can help you get further in your career.
